LOUIS COTE, OF ST. HYACINTHE, QUEBEC, CANADA.

HEEL-COUNTER MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,459, dated May 11,1886.

Application filed June 29, 1885.

T0 aZZ whom it may concern: Be it known that I, LOUIS COTE, of the cityand county of St. Hyacinthe, Province of Quebec, Canada, have inventednew and useful Improvements in I-IeeLCouriter Machines; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

This invention has reference to a further improvement in the inventionfor which two Letters Patent of the United States were granted to me,one dated June 19. 1883, numbered 279,717, and the other dated September23, 1884, numbered 305,427.

The particular feature or features which form the present invention willbe hereinafter fully set forth and claimed.

In the drawings hereunto annexed, similar letters of reference indicatelike parts, and Figure 1 represents a portion of a mechanism embodyingmy invention. Fig. 2 is an end elevation of the mechanism shown inFig. 1. Fig. 3 is a diagram of the old method of ar ranging themechanism heretofore in use. Fig. 4. is a diagram of a heel-stiffener,in which the results produced by the present invention as compared withthose of the old are shown. Figs. 5 and 6 are diagrams which illustratethe endeavors made to overcome the difficulty which my present inventionis arranged to surmount.

- Letter A represents the frame-work, O the shaft, D the former, E themold, all constructed, arranged, and operating as referred to in my saidprevious patents, and for further clearness of understanding arerefelrcd to by the same letters of reference.

Heretofore the former D and mold E have been set in relation to eachother concentric with the center upon which the former D revolves, asshown in Fig. 3that is to say,with the space F parallel or with therecess in the mold E concentricwitl' the outer surface or periphery ofthe former D, as shown, or by raising or lowering the said mold, asexplained in the said patents, to agree with what is required for thevariations of thickness of material out of which the heel-stiffener isformed, which adjustment being made in a vertical direction would stillleave the space F on the side G equal to that on the side H. Many of theheel-stiffeners produced by this arrangement of the mechanism arewrinkled or creased Serial No. 17(l,125. (No model.)

011 their upper edge, as indicated by the dotted lines J in Fig. 4. Theyalso have the objection that they are over duly contracted upon theupper edge, as indicated by the dotted line K in Fig. 4, instead of theconfiguration shown by the solid line L,which approximately fits thelastof an ordinary-formed boot or shoe. To obviate this objection along timeand many expedients have been devised, the most suitable of which hasbeen to cut the stock out of which the counter or stiffener is to beformed to the configuration shown in Fig. 6, instead of cutting it tothe configuration shown in Fig. 5, by which it will readily beunderstood that a larger amount of stock is consumed in the constructionof a given number of heel-stiffeners, and that the difficulty of havingthe wrinkles or creasesJ is not overcome thereby.

I find that by setting the former D,as shown in Fig. 1, eccentric to themold E, and by passing the pieces of stock out to the configurationshown in Fig. 5 in such a manner that the curved upper edge, M, will beacted upon by the narrower or closer part N of the space F, while thestraight side 0 passes through the wider part of the spaceF,perfect1y-formed counters or heel-stifi'eners are obtained there by,having the configuration shown by the line L instead of that shown bythe dotted line K, and free from the objectionable wrinkles or creasesJ, as indicated in Fig. at. This relative situating of the former andmold may be obtained .by an adjustment of the mold or an adjustment ofthe former in a longitudinal direction of the axis upon which the formerD revolves. Either or both of these methods of adj ustment may beemployed, and both of them are delineated in Fig. 1.

By placing the seat of the mold E in a slotted hole, Q, and providingadjustingscrews R, this adjustment may be obtained; or by providing theshaft C with a collar, T, and outer collar,U, and providing the axiswith a journal revolving in a screwed bush A,which screwed bush isfitted to a corresponding screwed bearing,]3,by screwing the bush A tothe position required the requisite adjustment of the former and moldwill be obtained, and after the bush A has been adjusted to the requiredposition the cap C of the hearing may be tightened down to secure theposition of the bush A.

I here wish to explain that with regard to the slotted hole Q and adjusting-screws R for obtaining an adjustment of the relative position ofthe former D with that of the mold E 011 the other means above describedfor this purpose, consisting of the screwed bush A and correspondingscrewed bearing B, such or any other means of adjustment are notnecessary when the machine is used for forming material of uniformthickness-such as leatherboardinto counters,in which case the positionof the mold E on the bed A may be an unchangeable one, and the former 1)being fixed in position on the shaft 0 no longitudinal movement of theshaft 0 need be provided for; but when the machine described is to beused indiscriminately on material of varying thicknessessuch as cuttingsof leather, or

vfirst on one thickness of leather-board and LOUIS COTE.
